strformatrt.cpp@ 80496

Last change on this file since 80496 was 80496, checked in by vboxsync, 5 years ago
IPRT/string.h: Added added two more human readable size formatting variants for skipping the 'i' in 'KiB' and such. Made the human readable size formatting use the space format flag to specify a space between the value and the unit.
Property svn:eol-style set to `native` Property svn:keywords set to `Id Revision`
